The number of deaths caused by smoking is set to rise dramatically by 2030

Health experts say tobacco use is the single biggest preventable cause of death globally.

And low to middle income earning countries will be hit harder by the rise in fatalities.

The joint report between the WHO and U.S. National Cancer Institute said around 80 per cent of smokers live in such countries, and although smoking prevalence was falling among the global population, the total number of smokers worldwide is rising.

There are more than 4,000 chemicals in tobacco smoke, of which at least 250 are known to be harmful and more than 50 are known to cause cancer.

Smoking is one of the biggest causes of death and illness in the UK with around 100,000 people dying each year, according to the NHS.

It is linked to a range of diseases including heart disease, heart attack, stroke, bronchitis and emphysema, pneumonia and cancers in the mouth, lips, throat, larynx, oesophagus, bladder, kidney, liver, stomach and pancreas.

The World Health Organisation is calling for governments to do more to prevent smoking

The World Trade Organization is expected to rule on the complaint this year.

Meanwhile, Australia’s policy is being closely watched by other countries that are considering similar policies, including Norway, Slovenia, Canada, Singapore, Belgium and South Africa.

Only one in three countries, representing a third of the world’s population, monitors tobacco use by repeating nationally representative youth and adult surveys at least once every five years, according to the WHO.

But for now there is no magic cure if you want to quit smoking.

Robert West, Professor of Health Psychology at University College London told The Sun: “Nicotine replacement therapies, including gums, can help — more than 100 studies say so. But they are no magic cure.

“Studies show smokers have a better chance of quitting using a nicotine patch combined with one of the others, such as gum or lozenges.

“And it’s vital to accept a lot of willpower is needed. All nicotine replacements do is reduce the cravings and mood swings a bit.”
